Hi!
So I've started interning at a local shop, and soon will be taking classes, to become a mechanic
I asked two guys about the infamous tv bushing issue.
I actually didn't even know what it did. For the first time I got to see my car up on a lift, and that was educational. There's lots you don't notice, because it's so inconvenient crawling around on your back with just 15" of jackstand clearance!
So I understand, now, that what it does is link the throttle to a set of linkages that force the transmission into the next lower gear when the throttle is wide open-- i.e., when you accelerate hard. "passing gear." Don't laugh! I didn't know about "passing gear" last week
SO. If that linkage breaks, why, really, should there be any negative consequence? You lose your automatic passing gear, so if you're in overdrive, your engine will start lagging as it can't maintain the torque to accelerate to pass. The correction, at worst somewhat inconvenient, would be to force the car out of overdrive and into drive, and once you've gotten in front of the car you're passing, shift it back into overdrive. And keep it in drive when first coming up the entrance ramp.
I don't see how this can destroy your transmission in 20 miles if it comes undone. I only see that you'll have a hard time getting onto the freeway unless you downshift manually.
Yet it's happened to people, who ruined their transmissions.
What I am missing in my understanding of how it works/ what it does?
thanks!!
